Working in partnership to make Dorset safer 9 PPE (continued) When working in or near water, the fire helmet chin strap should be left done up subject to dynamic risk assessment (DRA)and analytical risk assessment (ARA). When working at height near water, use the DRA and ARA to determine the outcome of a fall into water and to decide whether the chin strap should be undone or done up. Assess the risk of a neck injury from entering the water from height with chin strap done up, compared to entering the water with the chin strap undone and the risk of a head injury from colliding with objects, for example boats, pontoons or rocks.
